Description: This report discusses China's greenhouse gas (GHG) emissions as well as the policies and programs that they have put in place to mitigate them. These issues affect how Congress considers envionmental policies and relations with China.

Description: This report presents a chronology of major federal agency actions related to environmental concerns following the decision of Massachusetts v. EPA; it particularly looks at actions of the Environmental Protection Agency (EPA). In Massachusetts v. EPA, the Supreme Court held that greenhouse gases (GHGs), widely viewed as contributing to climate change, constitute “air pollutants” as that phrase is used in the Clean Air Act (CAA).

Description: This report presents a chronology of major federal agency actions, mainly by the Environmental Protection Agencey (EPA), in the wake of Massachusetts v. EPA. In this case, the Court held that greenhouse gases (GHGs), widely viewed as contributing to climate change, constitute “air pollutants” as that phrase is used in the Clean Air Act (CAA). As a result, said the Court, the U.S. EPA had improperly denied a petition seeking CAA regulation of GHGs from new motor vehicles by saying the agency lacked authority over such emissions.

Description: This report is intended as a primer on the policy issues, science, and governance of geoengineering technologies. The report will first set the policy parameters under which geoengineering technologies may be considered. It will then describe selected technologies in detail and discuss their status. The third section provides a discussion of possible approaches to governmental involvement in, and oversight of, geoengineering, including a summary of domestic and international instruments and institutions that may affect geoengineering projects.

Description: This report discusses the domestic and international efforts to increase foreign assistance to address climate change. Proponents maintain that such assistance could help promote low-emissions and high-growth economic development in lower-income countries, while simultaneously protecting the more vulnerable countries from the effects of a changing climate. The fundamental dispute concerning international financing for climate change centers upon who should pay for it and how.

Description: This report assesses the variables involved in determining whether or not biopower (i.e., electricity generated from biomass) is a carbon-neutral alternative to fossil fuels as a way to help meet meet U.S. energy demands and reduce U.S. greenhouse gas (GHG) emissions. It includes information about the biomass carbon cycle, GHG accounting for biopower production, recent developments affecting the assessment, and overview of whether or not it can be considered carbon neutral, and legislative implications.

Description: There are five common law/nuisance suits addressing climate change now or formerly active. Of the three no longer active, none were successful. Of the two still-active cases, one has recently leaped to center stage because the Supreme Court agreed to hear it. In Connecticut v. American Electric Power Co., Inc., eight states sued five utility companies alleged to be emitting the most GHGs in the nation through their coal-fired electric power plants. Following a Second Circuit decision, the Supreme Court agreed on December 6, 2010, to resolve threshold issues in this case.
